Cuckoo Maran chick keeps pecking larger Color Pack

[Esshea]

I just got a new batch of chicks from Coastal last week. 2 color packs and 2 cuckoo Marans. They were older so I got a good deal. They cuckoo marans shared a bin with some larger novagens at Coastal, one of the three marans kept pecking th neck of a bigger lighter novagen. There has been no pecking up until last night so I thought I got lucky and didn’t get the pecker. I was wrong!

The cuckoo maran is the smallest of the chicks and keeps obsessively pecking the neck of my largest chick. I have red light, plenty of room to escape heat of and the brooder is about 5’x3’ so I believe they have plenty of room. Any ideas to get this cuckoo to stop pecking Thanks!

Yes the smallest cuckoo Maran keeps pecking the neck of the biggest bird. The bigger chick ignores the Maran or flies away and roosts. I was told the birds could be bored so I added grass clumps and things to peck to no avail.
